Description
本発明に係る耐火ゴム組成物は、未加硫であることが必須であるが、具体的には、ツーローター式混練装置を用い80℃にて40回転/分の回転速度で5分間混練し、前記加硫剤及び前記加硫促進剤を添加し、さらに100℃にて前記回転数で5分間混練する混練処理工程ののちにも、針入度が30〜65度であり、かつ、加硫度が5%以下であれば好ましい。
また、前記混練処理後、50℃雰囲気下で120日ののち、加硫度が70%以上であるとより好ましい。
本発明に係る耐火ゴム組成物に含有される前記難燃剤は、難燃効果を有するものであれば特に限定されないが、一例としては、リン化合物を挙げることができる。
該リン酸化合物の種類も特に限定されないが、例えば、ポリリン酸アンモニウム類を含有させることができる。
更に、該ポリリン酸アンモニウム類の種類も特に限定されないが、一例としては、ポリリン酸アンモニウム又はポリリン酸アンモニウムアミドを挙げることができる。
本発明において「未加硫」とは、加硫性を有するものが未だ加硫されていない状態を示し、加硫性を有さない「非加硫」とは異なる概念である。
本発明に係る耐火ゴム組成物は、液状ゴム30〜60質量部、ブチルゴム40〜70質量部からなるベースゴム成分と、該ベースゴム成分100質量部に対して、粘着付与剤を3〜50質量部、熱膨張性黒鉛を10〜100質量部、難燃剤を30〜180質量部、無機充填剤を30〜210質量部、加硫剤を0.1〜10質量部、加硫促進剤を0.1〜10質量部を少なくとも含有し、未加硫の状態の組成物である。
本発明に係る耐火ゴム組成物は、好適な柔軟性と粘着性を有し、更に、好適な自然加硫性を備え、適切な加硫速度と十分な加硫後の強度を発揮するとともに良好な難燃性を有するため、未加硫のまま成形される耐火被覆材に好適に用いることができる。
本発明に係る耐火被覆処理方法は、前記耐火被覆材の特性を利用したものである。まず、前記耐火被覆材の有する粘着力に基づいて基材表面へ粘着させる。前記耐火被覆材は粘着性を有するため、従来の防火用膨張材料と異なり、鉄骨や壁等へ貼り付ける際に、接着剤、釘、ピン、ネジ等を用いる必要がない。また、粘着状態の耐火被覆材は、柔軟性を維持しているので、一旦基材表面へ貼り付けて位置決めを行った後にも、再度、剥離して貼りかえることが可能である。
(1)液状ゴム:ポリブテン;BP Japan(株)製、「H−300」
(2)ブチルゴム:JSR(株)製、「ブチル268」
(3)粘着付与剤:テルペン系樹脂;ヤスハラケミカル(株)製、「YSレジンPX−100」
(4)熱膨張性黒鉛:エア・ウオーター・ケミカル(株)製、「SS−3」(熱膨張開始温度220℃)
(5)亜リン酸アルミニウム:太平化学産業(株)、「APA―100」
(6)難燃剤:ポリリン酸アンモニウムアミド;太平化学産業(株)、「タイエンS」、ポリリン酸アンモニウム;クラリアント社製、「AP−422」
(7)無機充填剤:クレー;(株)群馬長石御座入鉱山製、「FA−80」、炭酸カルシウム;備北粉化工業(株)、「ホワイトンSB」、カーボンブラック;旭カーボン(株)製、「#80」、水酸化アルミニウム;昭和電工(株)製、「ハイジライトH31」、フライアッシュバルーン;巴工業(株)製「セノライトSA」
(8)加硫剤:粉末硫黄(細井化学工業(株)製)
(9)加硫促進剤:ジメチルジチオカルバミン酸亜鉛;大内新興(株)製、「ノクセラーPZ」、ジ−n−ブチルジチオカルバミン酸亜鉛;大内新興(株)製、「ノクセラーBZ」
(1)熱膨張倍率:試験片を300℃で保持された雰囲気内に0.5時間放置した後の膨張倍率を測定した。
(2)加工性:カレンダー成形機で試験片を成形する際に、問題なく成形できたものを「良」、外観不良発生あるいは安定した成形が出来なかったものを「不可」と評価した。
(3)形状安定性:熱膨張倍率測定後の試験片の形状を目視と指触で評価した。型崩れせず指で触っても崩れないものを「良」、指触ですぐ崩れるか、あるいは既に崩れてしまったものを「不可」と評価した。
(4)燃焼抑制効果:電気炉((株)デンケン製、KDF−S90)を600℃に昇温し、上記試験片を炉内に入れた後扉を閉め5分間放置。その後開閉し内部の試験片の燃焼状態を目視で観察した。試験片の燃焼が30秒間以内に収まった場合を「良」、30秒間以上継続した場合を「不可」と評価した。
(5)針入度:JIS K2207に準拠し荷重100g、温度25℃において測定を行った。規定の針を試験片に垂直に貫入させ、その深さを0.1mm単位で測定した。
(6)加硫度:JIS K6300記載の方法で、キュラストメーターIII型(JSRトレーディング社製)でトルクを測定した。加硫度(%)=(MX−ML)/(MM−ML)×100(MXはある期間を経た材料のトルク値、MLは測定曲線におけるトルクの最小値、MMは測定曲線におけるトルクの最大値)
(7)T型剥離接着強さ:JIS K6854の剥離接着強さ試験方法に準拠して接着強度を測定した。大きさが縦25mm×横150mm×厚み2mmのSUS板に試験片を挟んでハンドローラーで圧着した。貼り付け直後及び50℃オーブン中に4ヶ月放置後において剥離速度を50mm/minとし、T型剥離接着強さ試験を行った。
果も欠いていた。
